Abstract: A method for processing a flight plan, implemented in a flight management system, consisting of at least one segment, comprises a step of determining the positions of the start point and of the end point of each of said segments constituting said flight plan by searching for at least two characteristic points of said segment, said characteristic points being explicit, fixed and non-floating, said positions being respectively characterized by a latitude, a longitude and an altitude.

Abstract: An onboard flight management system in an aircraft comprises means for continuously calculating first geolocation data, from data received from at least one external geolocation device, comprising a current position and future positions of an aircraft along a trajectory sequenced in several portions and comprising second data comprising demands required by an international navigation procedure called “Required Navigation Performance”, or RNP, for all the portions of the trajectory. The management system additionally comprises a means for displaying first and second data all the way along the trajectory, the first and second data being represented graphically and simultaneously on the said display means in order to enable the pilot to anticipate the flight characteristics for the aircraft and make them converge toward the required demands of the next trajectory portion.

Abstract: A method for constructing a flight trajectory of an aircraft, comprises a step of computing a sequence of state vectors (Ei) representing the trajectory of the aircraft; a state vector (Ei+1) being determined on the basis of the state vector (Ei) preceding it by means of: a step of computing the speed components (Vi+1), consisting in determining: a flight setpoint, by selecting an objective navigation point, a joining strategy adapted to the flight setpoint and to the flight domain (DV) by means of a predefined library (LSr) of joining strategies, a manoeuvre by means of the flight domain (DV), making it possible to follow the joining strategy towards the flight setpoint; a step of computing the other components of the state vector (Ei+1), on the basis of the components of the speed vector (Vi+1) and of the preceding state vector (Ei).
